Walk down any high street in Birmingham, Manchester or Leicester on a Friday night and count the menus with “smash” on them. Five years ago it was a novelty. Now a takeaway without a smash burger looks like it has stopped paying attention.
The good news is that a smash burger is one of the simplest things a kitchen can put out well, and one of the most profitable. The patty is small, the cook time is short, and the flavour comes from technique rather than expensive ingredients. The bad news is that most of the advice online is written for people cooking four burgers in a garden, not four hundred on a Saturday.
This guide is for the second group. It covers what a smash burger actually is, which patty weight suits which menu, how to season and smash for a proper crust, and why the sauce matters more than the bun. Home cooks are welcome to read along too: every product mentioned is available in single units from the BurgerPro shop.
A smash burger is a thin beef patty pressed hard onto a very hot flat-top or griddle the moment it lands, so that the maximum surface area of meat hits the metal. That contact produces the Maillard reaction: the browning that gives a smash burger its craggy, lacy, almost crisp edges and deep savoury flavour.
Because the patty is thin, it cooks through in around 90 seconds a side. There is no pink middle to worry about, no probe thermometer, and no customer sending it back because it is “too rare”. Unlike a classic burger, two thinner patties give you more browned surface and better layering than one thicker patty. It is a fast-food format in the best sense: fast to cook, consistent every time, and built for volume.
The classic build is two thin patties, American cheese, pickles, onion and a burger sauce in a soft bun. But a single patty with sauce and a slice of cheese is a perfectly good value option, and doubles and triples are where the margin lives.
The most common question we get from operators is about weight. There is no single right answer, but there is a right answer for each menu.
A 2oz patty is the traditional American smash size. It is too small to sell on its own for most UK customers, but it is the ideal building block for doubles and triples. Two 2oz patties give you a 4oz burger with twice the crust and twice the cheese contact of a single 4oz patty, which is exactly why smash doubles taste better than ordinary quarter pounders.
BurgerPro stocks HMC 100% Smash Burgers at 15 x 57g (2oz) in both standard and Angus versions. If your menu is built around “double smash” as the default, this is the box to start with.
At 70g, a single patty is a credible kids’ or value burger, and a double lands at 140g, which most customers read as a proper meal. This is the weight we recommend if you want one patty to cover the whole menu without running two lines.
Available as HMC 100% Smash Burger 12 x 70g (2.5oz) and the Angus 12 x 70g for a premium listing.
Some kitchens want a single-patty smash that still feels substantial, particularly cafés and pubs where the customer is not expecting a stacked double. The HMC 100% Smash Burger 12 x 85g (3oz) is the one for that job. It still smashes thin enough to crust properly, but you only need one on the griddle per order.
Work out your best-selling build first, then buy the weight that makes it in one or two patties. Running one weight keeps the freezer simple, keeps portion cost predictable and stops staff reaching for the wrong box during a rush.
Purists will tell you a smash burger must start as a loose ball of fresh mince. In a home kitchen, fine, and if you do go that way, chuck mince with around 20 per cent fat gives the best flavour and juiciness. In a takeaway doing 300 covers, fresh mince means daily prep, weighing every portion, a shorter shelf life and a food safety burden you do not need. The patties also need to stay well-chilled before cooking to keep their texture and juiciness.
Pre-formed frozen pucks solve all of that. Every patty is the same weight, so your cost per burger never drifts. They go from freezer to griddle with no handling. And because the patty is already a compact disc, it smashes evenly rather than squashing out one side.
BurgerPro’s HMC smash range is manufactured in Ireland by a supplier with 27 years of experience producing patties for McDonald’s, which tells you everything about the consistency you can expect. The full frozen line-up is on the burgers page.
Here is the method that works on a commercial flat top griddle. At home, the same cues apply in a hot cast iron pan, because cast iron holds heat well. The ingredient list is short on purpose.
You need: frozen smash patties (or, if you are forming your own, beef mince with about 20 per cent fat), a neutral high-heat oil or beef dripping, seasoning, American-style cheese slices, soft buns, and your sauce.
From patty landing to burger in the box should be under three minutes. That speed is the whole point of the format.
The most common seasoning mistake in takeaways is over-complicating it. Good beef, hot metal and salt do 90 per cent of the work. A basic blend of salt, black pepper, garlic powder and onion powder is plenty, and a little smoked paprika adds colour without changing the flavour much.
If you want a signature flavour, put it in the sauce, not the seasoning. Customers taste sauce far more than they taste a dusting of spice on a 2oz patty, and it is far easier to be consistent with a squeeze bottle than with a hand shake of powder during a rush.
A smash burger has a huge amount of crust and very little fat compared to a thick patty, so it needs something creamy, tangy and slightly sweet to balance it. That is why the classic pairing is a pink burger sauce built on mayonnaise, ketchup, mustard and pickle. A good special sauce adds to the standard toppings rather than replacing them. Nobody buys a smash burger for the bun; they buy it for the combination of crust, melted cheese and sauce.
BurgerPro stocks several ready-made burger sauces that do the job without a prep list:
A useful menu structure is one house smash sauce as the default (Biggy or Big Burger), then two named alternatives customers can swap in at no extra charge. It costs you nothing, it makes the menu look considered, and it gets people trying sauces they will then ask for by name. For more on matching sauces to patties, see the burger sauce pairings guide.
A smash burger menu does not need to be long. Four or five builds using one patty weight, one cheese, one bun and three sauces will outsell a fifteen-item menu every time, because the kitchen can produce it fast and the customer can decide fast.
A starting menu might look like this: a single smash with cheese and house sauce; a double patty smash as the headline; a triple for the hungry; a “spicy” double with Algerian sauce and jalapeños; and a loaded fries option using the same patties crumbled over Aviko fries with cheese sauce. Every item shares stock. Nothing sits in the freezer waiting for one order a week.
If your customers expect halal, the HMC certification on the smash range does the reassurance for you. Say it clearly on the menu and on your online ordering listing. Our post on halal burger sauce essentials covers the sauce side of that question.
For a takeaway, 2oz (57g) or 2.5oz (70g) patties served as doubles are the most popular. A 3oz (85g) patty suits a single-patty smash. Pick one weight and build the menu around it.
No. Pre-formed frozen smash patties give you consistent weight, no daily prep and a longer usable life. They smash and crust exactly as fresh mince does on a properly hot griddle. If you are forming your own at home, chuck mince with about 20 per cent fat works best.
The HMC 100% Smash Burger range, including the Angus versions, carries HMC certification. Check the individual product page for the pack you are ordering.
Hot enough that a drop of water evaporates almost instantly; for home cooks, that means a cast iron pan rather than a non-stick one, which struggles to hold the heat. If the patty does not sizzle aggressively the moment it lands, the plate is not hot enough for a crust.
Salt and black pepper, with garlic and onion powder if you like. Keep it simple and put your signature flavour into the sauce instead.
A creamy pink burger sauce is the classic. The same sauce works on fries and wraps, so one bottle covers several menu lines. Nawhal’s Biggy Burger and Colona Big Burger are ready to squeeze. Algerian and Samurai are the most popular spicy alternatives.
The 2oz HMC smash burgers come 15 to a pack. The 2.5oz and 3oz packs contain 12 patties each. Case quantities for trade orders are confirmed through the wholesale enquiry form.
